■'Little is presented- that is neyr or original, Rather the book 
attempts to strip dov'/n the comiplexit^^ of contributions in the field 
of conservation to some of the more essential elements .Three concepts 
are considorcd to form the basis of the conservation movement t (l) That 
soil,y.rator, forest and wildlife conservation are orily parts of one in- 
separable program: (2) that wildlife must have an onxrLrorarient suited to 
its needs if it is to survive; and (3) that e.ny use that is made of any 
living resource m.ust be limited to not m.ore than the annual increase 
if the essential seed stock is to be continually available. Tliese three 
concepts are the basis of presert ^vildlife and forest conservation
